Oxidation Ditch Upgrade Guide: Disc Rotor Conversion for Improved DO, Energy Efficiency & TCEQ Compliance
This technical memo explains how municipal wastewater treatment plants can restore dissolved oxygen (DO) performance in oxidation ditches by upgrading from brush rotors to high-efficiency disc rotors. Designed for WWTP engineers and operators facing summer loading challenges or tightening TCEQ discharge limits, this guide outlines how removable disc aerators improve oxygen transfer, increase mixing, and reduce energy consumption.
Learn how Envirodyne Systems Inc. (ESI) Disc Rotor technology provides a plug-and-play retrofit within the existing footprint—often reusing the torque tube—while delivering increased aeration capacity, extended mechanical life, reduced misting, and lower maintenance requirements.
Ideal for Texas municipalities evaluating oxidation ditch retrofits, brush rotor replacement, new construction cost savings, or energy-efficient aeration upgrades.
Oxidation Ditch Retrofit Guide: Retrievable Fine-Bubble Aeration for WWTP Compliance & Energy Savings
This technical memo outlines how municipal wastewater treatment plants can restore dissolved oxygen (DO) performance in aging oxidation ditches using retrievable fine-bubble aeration systems. Learn the difference between supplemental aeration upgrades and full process conversions, and how Jaeger-Aeration’s OxyLift™ and OxyStrip™ systems meet TCEQ 317 requirements without basin dewatering or redundant basins.
Includes Texas project references, performance data, and case studies demonstrating up to 50% energy savings, improved TN/TP compliance, and zero-downtime installation.
Ideal for WWTP engineers, operators, and consulting engineers evaluating oxidation ditch upgrades, aeration retrofits, or energy-efficient process improvements.
Let’s take a look at our Oxidations Ditch Fix. Here you will learn about our system and the manufacturers we use to mitigate your oxidation ditch issues.
Let’s take a look at our Aeration Upgrade Approaches. Here you will learn about our system and the manufacturers we use to mitigate your Aeration Upgrade Approaches issues.
Let’s take a look at our Hybrid Blowers. Hybrid refers to two different types of positive displacement (PD) blowers. Those two types are the screw impeller and the twisted tri-lobe impeller PD blowers. The purpose of this tech memo is to illustrate the differences and define the proper application range of each.
The best feature of both types of blowers is that they do not surge.

This memo compares aeration basin options for WWTPs up to 2.0 MGD, noting that while SBRs were once cost-effective, reduced supplier competition and higher lifecycle costs now make conventional treatment more favorable.
This memo compares APG NX and ABS HST turbo blowers, highlighting APG’s superior efficiency (7–11% higher), U.S.-based manufacturing and service, and simpler installation. In contrast, ABS units require more piping and HVAC runs, adding hidden construction costs and requiring taller ceiling clearances.
